Applieaton filed October 2, 1916. Serial No. 123,380.

To cil whom t may concern: Y

Be it known that I, REA P. l/VRIGHT, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Adjustable Automatic Pressure-Roll Releases for ClothesNVringers, of which the following is a specification, reference being had therein to the accompany ing drawing.`

rihis invention relates to certain new and useful improvements in adjustable automatic pressure' roll release for clothes wringers, the object being to provide an automatic release which can be readily attached to a clothes wringer ot the ordinary construction so that the pressure on the pressure rolls will be instantaneously released when the upper pressure roll moves a predetermined distance.

Another object of my invention is to provide an automatic release which is exceedingly simple and cheap in construction and one in which the releasing bars are slidably mounted on the wringer frame so as to cooperate with pivoted latches for holding the pressure means inpredetermined position7 .said releasing bars carrying adjustable fit mounted members which are engaged by the shaft of the upper pressure roll when the same is moved vertically by a foreign object being drawn between the rolls.

Another and further object of the invention is to provide en automatic pressure release which can be adjusted on the pressure rolls when the upper pressure roll moves a certain distance upwardly, whereby the wringer to which the pressure release is attached can be used for wringing various thicknesses of clothes by adjusting the release. u

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

in the drawings,

Figure 1 is a s'idelview of the wringer part-ly in section showing the application of my improved construction of automatic pressure release thereto; f. i

Fig. 2 is an endl view;

is a detail perspective vie'wof the automatic release detached the Pertsi being separated;

e is a detail sectional' vi slightly modified form showingl the bearing 30 on the upper pressure roll extended in position to engage the adjustable trip member 32 carried by the releasing bars.

Like numerals of reference refer to like parts in the several figures of thev drawings.

In the drawings7 1 `indicates a wringer 'frame composed of side bars 2 connected together at their lower ends by cross bars 3 and a rod 1, said siehe bars being provided with slotted upper portions in the upper end of which is movably mounted a top bar l5.

Slidably mounted within the lower por tions of the slotted side bars 2 aresuperposed bearings Y and 6 in which are'mounted shafts 7 and 8 carrying pressure rolls 8 and 9 which are preferably provided with meshing gears, not shownA` inclosed by gearv The upper bearings. 6 carry* spring supports 11 on which are mountedv casings 10.

pressure springs 12 into which extend'jthe depending lugs of bearing plates/13 carried by a pressure bar 14, said bearings 13 being engaged by pressure screws 15 mounted in threaded boxes carried by the top bar 5 so that the pressure means on the pressure rolls can be adjusted through the medium of these pressure screws. Y

Extending intov the slot of the side bars transversely are screws 16 which extend into the apertured ears 17 of pivoted latches' 18 which are adapted to engage the end of the top bar 5 as clearly' shown in Fig. 1 so as to hold the top bar in position within the slotted side bars of the wringerframe. The latches 18 are provided with curved por tions forming cam faces 19 which are adapte ed to be engaged by the cam-shaped upper ends 2O of releasing bars 21 which are slidably mounted in guide members 22 secured to the side bars, said releasing bars`21 carrying pins 23 working in slots 21l'lformed in the guide members 22 for holding the releasing bars in predetermined position in respect to the pivoted latches 18. The lowerv ends of' the releasing bars 21 lare oi'set as shown at 25 and are provided wit apertures 26 in which bolts 27 are arranged on which are slidably mounted trip members 28 with slots through which the bolts 27 extend, said bolts carryirig thumb nuts 29 Jrior clampingk the trip members 28 in adjusted position upon the lower ends of the releasing bars 21 so that the lower edges thereof can be adjusted in respect to the ends of theshaft 8 or theupper pres- 'sure roll 9 so as to Vallow the wrlnger to so that when the. upper pressure roll is` moved vertically by a foreign object passing between the rolls, the extended portion 31 will engage the trip member 32 so as to raise the releasing bar and move the pivoted latches out of the path of travel of the top l bar to release said pressure means.

The operationof the automatic pressure roll release as herein shown and described is as follows: I

Assuming that the wringer is being driven by power or hand through-the medium 'of driving mechanism, not shown, carried by the lower shaft 7 ofI the pressure roll 8 when a foreign object is drawn between the pressure rolls the upper pressure roll 9 is moved vertically and the shaft 8 thereof is forced into engagement with the lower edge of the trip membersY 28 which causes the `trip members to move vertically in order to bring the cam-shaped upper ends 20 into engagement with the cam faces 19 of the pivoted latches 18 which forces said latches outwardly from 0E of the Vends of the movably mounted top bar 5 and allows the top bar 5 to move vertically which instantaneouslyreleases the pressure on the pressure rolls.

From the foregoing description it will be seen that I have provided an automatic pressure roll releasey for clothes wringers which can bel'set so Ithat the same will be tripped by the' vertipal movement of the upper pressure roll,I wherebyl am able to set the releasingmechanismv into various posi- :tions in. order to enable. the clothes wringer to wring dierent articles without releasing the pressure roll means.
